Here's my system information but I don't know if it will tell us much: cpu: P4 1.5G ram: 512M hdd: 60G IDE o/s: Windows XP Pro SP1 pte: v4.10 If I create a brand new slide show by going to "new" on the file menu I don't get the error message when clicking "exit" on the startup window. But my test slide shows do not have as many slides. I began this large job, the one giving me this trouble, in one of the recent betas, I believe 4.10 #10. Here are the job stats: synchronization: yes transitions: fades various length number of images: 327 .jpg 800x600 startup image: .jpg music: 5 .mpg files length: 17:40 Because of time constraints I have gone ahead and finalized this job leaving off the exit button. Not preferred but what else could I do? Except to redo the job completely from scratch, which was not an option. Any thoughts would be appreciated but it looks like this may be one of those esoteric things. I wonder if any clue can be derived from the error message itself? johnny
